the light is visible to the naked eye ? What is the angle of light beam from 20-30 feet ?

Its infrared, so it isn't visible to the naked eye. Anyone with bc can see it. At 30ft the beam is 1'

No....not visible to naked eye. Used in conjunction mainly with night vision equipment. Beam is a hot spot with a nice halo as with most LED lights. Excellent light and does a great job for me. I use it mounted above a rifle scope to shoot hogs at night with my night vision gear. Highly recommend this product. You will not be disappointed if you have an application for its use.

No it's infrared, all you see is a low red glow from the bulb. Not sure about angle, probably about 10 ft across.

If you look directly into the device, there will be a faint res dot. You can not see any light otherwise. It will throw out to about 150 yards effectively, maybe a bit more. There ia about a 30 degree angle either side od center.

It is not narrow. 6 feet away the beam cone is about 6 feet in diameter I would estimate. Area lighting not spot

I believe it is the spread of light 30 degrees would be more narrow beam of light and 60 would spread out twice as much. 30 seems to be good for driving at night. As long as you remember to turn off the lights before an on coming car gets within a 3/4 of a mile My friend said that even at a mile they were bright to oncoming traffic.

It's the width of the light beam. 60 being twice as wide as a 30 degree light. Therefore, 30 is more of a spot light and 60 more of a flood light.

Not sure of the angle since I do not have any trig tables in front of me. The fully illuminated spot is about 14" in diameter at 23" distance; with some diminishing light present for several more inches around the bright spot.

Well,the heat has nothing to do with the degrees of the output angle of the light.I think you have the degrees mixed up with heat .30 degree led is like a spot light, the 60 is a flood light.hope this helps

Its more of a area of light affect instead of just a beam of concentrated light. I can see about 30 - 40 feet when in darkness with this light. I am still very happy with this light. Still on the same set of batteries with it as well.

I'm not too sure but my guess is high beam (depending onew your current eye health) about 100 feet .One can however pick up reflective road signs well beyond that it's amazin.. As far as being seen. .....it's unreal , if someone can say you weren't seen from at least a mile they gotta have serious challenges

I dont know the exact range but my lights will detect motion at least 20 feet away

The beam angle is 38 degrees. (see the following for more details: http://www.feit.com/led-lamps/performance/dimmable/reflector/par38-wp-led)

The smaller light is sufficient to see within 30 feet but is not overly bright. The LED is much brighter and useful as a spot and will project well up to about 100 feet.

The light covers approximately a 20 foot area. One light won't cover a large yard.

10 yards is the peak brightness. At that distance they hurt your eyes, and traffic hates me which is why I bought them for my motorcycle. I want to be seen! The exact angle I can not determine. it is a very tight pattern that does not spread out until about 45 feet.

No easy answer, how high R U going to mount your light?????? I can say 25/30 feet would be a safe estimate....equally wide.

Its either 130 or 180 lumens. Its very bright and you can focus in the beam.

A few feet. This is a very tiny light designed to illuminate an area at arm's length. It works great as I'm climbing through crawlspaces or working on top of dark ductwork. But I certainly wouldn't use it for lighting distances such as for jogging or cycling.

The light angle is at least 150 degrees although not as bright at the edge.
